Abstract: 1,239,777. Removing metal by fusion. NATIONAL RESEARCH DEVELOPMENT CORP. 1 Oct., 1969 [3 Oct., 1968], No. 46938/68. Heading B3V. [Also in Division H1] A workpiece 19 is shaped by projecting a constant intensity portion of a laser beam through the transparent parts of a mask 17 so that an image is formed on the workpiece 19 of at least part of the mask 17. The laser beam 11 from a ruby laser 10 is diverged by passing it through longitudinally movable concave lenses 13, 14 and passed through a filter 15 to attenuate the beam. After passing through a lens 18, the beam is passed through the mask 17 to cause numerals to be projected via a lens 21 on to the workpiece 19 comprising a metal film, e.g. Al, Ag, Ti on a substrate. The film is evaporated at areas of the image corresponding to transparent areas of the mask 17. Material may alternatively be deposited on the workpiece 19 by placing a gelatine film with an emulsion or coating of the material to be deposited in contact with the workpiece 19. The apparatus is provided with a viewing and alignment microscope 24, television viewer 25, a beam splitter 22 which is used with an autocollimator 23 or gas laser for checking coincidence and indexing means 31, 32 for the mask 17 and workpiece 19 so that different profiles can be machined on different parts of the workpiece. The laser 10 is operated in the burst mode wherein each pulse envelope has a rise time of 150-500 microseconds controlled by a capacitor C n  and inductor L n  forming part of a delay line connected to a D.C. source 48 and a flash tube 47 for pumping the laser 10. Each pulse has a duration of 1-8 milliseconds controlled by the total capacitance and inductance of the delay line. The energy of the burst is 0À1-10 joules.

Title: Method and apparatus for the formation of an alloy composed of metals reactive in their elemental form with a melting container
Inventor: BUEHLER WILLIAM JAMES
IPC: C22C1/02
Filed: 1967-11-03
Abstract: 1,213,611. Forming alloys. W.J. BUEHLER. Nov.3, 1967 [Nov.4, 1966], No.50167/67. Heading C7D. In forming an alloy containing at least one metal component reactive in its elemental form with a melting container, the alloy itself being relatively unreactive with the container, a pre-alloyed material of the same constituents as the alloy to be obtained is first melted in the melting container and the component elemental metals of the alloy are thereafter incorporated in the molten material in such a manner as to substantially prevent direct contact between the component elemental metals and the container walls. As shown in Fig. 2a, blocks of mechanically mixed and compacted elemental Ti and Ni are placed on a Ti-Ni alloy starter plate in such manner that the elemental Ti and Ni do not touch the sides of a graphite crucible. The crucible is heated by induction heating in such manner that the Ti-Ni alloy first melts and the elemental Ti and Ni melt into the molten alloy. To prevent tilting of the stack of blocks during melting, the blocks may be guided through holes in their centres by a pre-alloyed rod that is fastened in a vertical position above the crucible. Alternatively, they can be centred and fed vertically through an alloy tube. To prevent excessive weight of the stack causing the blocks to contact the crucible bottom when the alloy is molten, the blocks can be released from above one or more at a time to allow the molten alloy to float the block(s). Instead of using blocks, a rod of partially sintered mixed Ti+ Ni can be fed downwardly into the molten Ti-Ni alloy. Figs. 2b and 2c (not shown) illustrate the feeding of Ti and Ni particles into a pool of molten Ti-Ni alloy in a graphite crucible. In the Fig. 2b arrangement, the particles are metered into the molten alloy and in the Fig. 2c arrangement the particles are within a Ni Sheet can which is lowered into the molten alloy. The Ti and Ni particles may be in the form of sponge and shot respectively and Co or Fe may be added. The graphite crucible may be dried before use. The induction melting may be in a chamber under a pressure of from a few microns to more than one atmosphere, e.g. under an Ar or He atmosphere. Alloys which may be produced by the method are:- (a) 55À1% Ni, remainder Ti and impurities, (b) 60% Ni, remainder Ti, (c) 54À59-55À40% Ni, 0À033-0À042C, remainder Ti and (d) the alloys TiCo, TiFe, TiNiICo1-x, TiNix Fe1-x and TiCox Fe1-x.

Abstract: 1,128,907. Push-button tuning. PLESSEY (UK) Ltd. 6 Jan., 1966 [18 Dec., 1964], No. 51558/64. Heading H3Q. [Also in Division H1N] A receiver tuning arrangement covering different frequency bands has separate tuners mechanically coupled together so that the pushbuttons operate both simultaneously, the buttons also actuating switches to change the operating condition of the receiver where necessary, e.g. frequency-range and number of scanning lines in a television receiver. In Fig. 1 a V.H.F. tuner 1 of the spring-urged inductance core type as in Specification 989,781 and a U.H.F. tuner 2 of the rotary capacitor type are coupled together by a mechanical linkage 10 which is attached to a crank 9 on the rotary capacitor shaft and operates a hinged plate 11 to move the plunger 3 axially. The tuning push-buttons 4-7 are located in the U.H.F. unit and when any one is pressed it operates both tuning controls simultaneously. Button 4 selects V.H.F. Band I, buttons 5 and 6 select two different U.H.F. channels and button 7 selects V.H.F. Band III. The V.H.F. tuner includes a slider switch for changing from Band I to Band III and another slider switch for changing from V.H.F. to U.H.F., and these are operated by the appropriate buttons 5-7 by means of a pivoted plate on a cross-shaft (12 in Fig. 2, not shown). At the same time buttons 5 and 6 move a plate (14) which engages a spring- urged slider (15) to operate the standards conversion switch (16). Fine tuning is effected by rotating the buttons 4-7 as in Specification 1,006,215. An additional on/off button 17 is interlocked with buttons 4-7 for latching and release. The rear end of this button carries a cam 20 with a conical portion 24 which engages a plate 21 to operate a pair of microswitches 22, 23 to complete the heater circuits. When the button is pushed in it operates an arm 19 to switch off the H.T. by a switch 18. If one of the buttons 4-7 is now pressed, the button 17 will be released and the H.T. will be switched on; since the heaters are already on the set will operate immediately, the heater circuit being maintained by switch 18. To switch off the set the button 17 is turned through 180 degrees and then pressed in; the plate 21 no longer operates the microswitches and the heaters are turned off.
